 ## Pipelines
 The entire build system is a composition of various asynchronous pipelines. The very first pipeline is the HTML pipeline. This directly corresponds to the source HTML file (typically the `index.html`), and this pipeline is responsible for spawning various other pipelines based on the directives found in the source HTML. As a reminder, Trunk uses the `<link data-trunk rel="{{TYPE}}" ..args.. />` pattern in the source HTML to declare asset pipelines which Trunk should process.
 
-Each pipeline is given all of the data found in its corresponding `<link>`, along with some additional general data, like config and such. This is then spawned off as an async task. Currently there are no dependencies between pipeliens, however the HTML pipeline will not complete until all of its spawned pipelines have finished.
+Each pipeline is given all of the data found in its corresponding `<link>`, along with some additional general data, like config and such. This is then spawned off as an async task. Currently there are no dependencies between pipelines, however the HTML pipeline will not complete until all of its spawned pipelines have finished.
 
 Ultimately, each pipeline can do whatever it needs to do, producing various artifacts and writing them to the Trunk staging directory. Once a pipeline finishes, it will return a manifest of data along with a callback. That callback is called by Trunk providing a mutable reference to the will-be final HTML, and that callback can update the HTML in whatever way it needs, which is typically just to remove its original `link`, and maybe append some new data which points to newly generated artifacts. Once all of the pipelines have completed, Trunk will perform a few final tasks to provide a nice pristine `dist` dir ready to be served to the web.

 Trunk ships with a set of CLI commands to help you in your development workflows.
 
 # build
+
 `trunk build` runs a cargo build targeting the wasm32 instruction set, runs `wasm-bindgen` on the built WASM, and spawns asset build pipelines for any assets defined in the target `index.html`.
 
 Trunk leverages Rust's powerful concurrency primitives for maximum build speeds & throughput.
 
 # watch
+
 `trunk watch` does the same thing as `trunk build`, but also watches the filesystem for changes, triggering new builds as changes are detected.
 
 # serve
+
 `trunk serve` does the same thing as `trunk watch`, but also spawns a web server.
 
 # clean
+
 `trunk clean` cleans up any build artifacts generated from earlier builds.
 
 # config show
+
 `trunk config show` prints out Trunk's current config, before factoring in CLI arguments. Nice for testing & debugging.

 Trunk supports a layered config system. At the base, a config file can encapsulate project specific defaults, paths, ports and other config. Environment variables can be used to overwrite config file values. Lastly, CLI arguments / options take final precedence.
 
 # Trunk.toml
+
 Trunk supports an optional `Trunk.toml` config file. An example config file is included [in the Trunk repo](https://github.com/thedodd/trunk/blob/master/Trunk.toml), and shows all available config options along with their default values. By default, Trunk will look for a `Trunk.toml` config file in the current working directory. Trunk supports the global `--config` option to specify an alternative location for the file.
 
 Note that any relative paths declared in a `Trunk.toml` file will be treated as being relative to the `Trunk.toml` file itself.
 
 # Environment Variables
+
 Trunk environment variables mirror the `Trunk.toml` config schema. All Trunk environment variables have the following 3 part form `TRUNK_<SECTION>_<ITEM>`, where `TRUNK_` is the required prefix, `<SECTION>` is one of the `Trunk.toml` sections, and `<ITEM>` is a specific configuration item from the corresponding section. E.G., `TRUNK_SERVE_PORT=80` will cause `trunk serve` to listen on port `80`. The equivalent CLI invocation would be `trunk serve --port=80`.
 
 # CLI Arguments & Options
+
 The final configuration layer is the CLI itself. Any arguments / options provided on the CLI will take final precedence over any other config layer.
 
 # Proxy
+
 Trunk ships with a built-in proxy which can be enabled when running `trunk serve`. There are two ways to configure the proxy, each discussed below. All Trunk proxies will transparently pass along the request body, headers, and query parameters to the proxy backend.
 
 ## Proxy CLI Flags
+
 The `trunk serve` command accepts two proxy related flags.
 
 `--proxy-backend` specifies the URL of the backend server to which requests should be proxied. The URI segment of the given URL will be used as the path on the Trunk server to handle proxy requests. E.G., `trunk serve --proxy-backend=http://localhost:9000/api/` will proxy any requests received on the path `/api/` to the server listening at `http://localhost:9000/api/`. Further path segments or query parameters will be seamlessly passed along.
@@ -30,6 +35,7 @@ The `trunk serve` command accepts two proxy related flags.
 `--proxy-ws` specifies that the proxy is for a WebSocket endpoint.
 
 ## Config File
+
 The `Trunk.toml` config file accepts multiple `[[proxy]]` sections, which allows for multiple proxies to be configured. Each section requires at least the `backend` field, and optionally accepts the `rewrite` and `ws` fields, both corresponding to the `--proxy-*` CLI flags discussed above.
 
 As it is with other Trunk config, a proxy declared via CLI will take final precedence and will cause any config file proxies to be ignored, even if there are multiple proxies declared in the config file.
